For a half- life, the formula is
A(t) = A0(0.5)^( t / t_0.5)
where A(t) is the amount of substance at time t
A0 is the initial amount of subtance
t_0.5 is the time it will reduce its amount to half
t is the time

substitute the given to the formula
A(t) = 100(0.5)^( t/6 )
so the decay factor is 0.5^( t/6 )

there were 50 cars parked at the airport car rental lot. Of those 50 cars, 10% were red. How many cars were red?
solmaris [256]
10% of the 50  were red.

10% * 50

(10/100) * 50

(1/10) * 50

= 5

5 were red.

3(2.4−1.1m)=2.7m+3.2
telo118 [61]

Hello again!

First, distribute the 3 to the parenthesis, so you get 7.2-3.3m=2.7m+3.2. Next, subtract 3.2 from both sides to get m's on one side. Then you have 4.2-3.3m=2.7m. Next, add 3.3m to both sides so you can solve for m. Now you have 4.2=6m. Then, divide 4.2 by 6, and m=.7

Hopefully this helps! Let me know if you have any questions
